AR15 zero irons first then red dot?
I'm not a newbie with AR15's at all, but I am with optics on them.
How should a guy sight in an AR15 with backup sights and a red dot?
This is a Vortex Strikefire with the tall mount. Also, should the red dot just sit on top of the front sight if the irons are sighted properly? Should you be able to look through the backup sight and see the red dot right in the middle on top of the front sight post?
